HYDRAULIC CONCENTBATOR Specification of Letters Patent.

Application filed December 22, 1911.

Patented July 2, 1912.

Serial No. 667,364.

To all whom it may concern:

Be it known that I, Unrssns A. Gamma, citizen of the United States, residing at Anaconda, in the county of Deerlodge and State of Montana, have invented certain new and useful Improvements in Hydraulic Concentrators, of which the ,following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention has relation to improvements in slime concentrators;and it consists in the novel features of construction more fully set forth in the specification and pointed out in the claims.

In the drawings, Figure 1 is a side elevation of'the apparatus, parts being broken away; Fig. 2 is a top plan, with parts broken away; Fig. 3 is a cross-section on the diagonal line 3-3 of Fig. 1; and Fig. 4 is an enlarged side view, with parts broken, of the lower portion of the supplemental receptacle which treats the concentrates dis charged from the primary receptacle.

The present improvement while appl1- cable to the treatment of various materials is particularly directed to the concentration of ore-slimes, the special obiect in view being to so manipulate the pup or slime carr mg the ore values as to not onlyeliminate t erefrom to the best advantage the light clay particles or colloids which are a great hindrance to the concentration of the ore proper, butto separate the ore values from lthe sandy components and gan ue remaining with the one after the colloi have been removed.

Stated in general terms the invention contemplates an apparatus in which the shines are subf'ected to a preliminary treatment m a vesse or container to. which there is imparted a rotary tion about a ver-.

tical axis, the slime introduced thereintointheformofa eetd sposed na plane at ri ht angles to said axis (that is to so. in a horizontal shoot), an asccndin co umn of water flowin the vesse durin the reci rocations' o the latter where y the lig t colloids are caused toflow over the upper edge of the vessel into a suitable launder, the sandy constituents and ore descending throu h the rising water column and discharging m the bottom of the vessel into a seeon container having a similar rotary reciprocation thereto, but preferably about an axis inclined to the horizontal, the ore concentrates and heavy values discharging through a hollow plug or spigot at the bottom of said vessel and the lighter gangue and sand flowing through the open end of the' vessel into a suitable launder. The apparatus however has identified therewith certain structura details the advantages of which will be better apparent from a detailed description of the invention which is as follows Referring to the drawings, C represents a suitable (preferably) cylindrical receptacle or container terminating in a bottom conical discharge hopper C. The receptacle wall is provided with an outer ring or flange "1 resting on ball-bearings 2 which traverse an annular race-way in a stationary ring 3 secured to the I-beams 4 and loosely encompassing the receptacle. The mounting of the receptacle in the manner. indicated (or any manner equivalent thereto) renders the same easily susceptible to rotary reciprocation about its vertical axis, this reciprocation being effected throu h a connecting rod or link 5 leading from t e eccentric 6 on a vertical drive-shaft S, the latter being provided with a pulley P for the accommodation of a belt B, leading to any suitable motor or engine not shown). No attempt is here made to illustrate the shaft hearings or means ofsupport for the shaft, as such details fall within the purview of the skilled mechanic.

Secured centrally within the receptacle 0 by means of straps or braces 7 (or otherwise) is a feed-funnel 8 from the lower end of-which dependsa pipe 9 closed at the bot the hopper C is a hollow swivel-joint 10 of any approved design, said joint forming the upper terminal of a stationary chamber 11 to which water under a head or pressure is admitted through the terminal upwardly turned nozzle 12 of a water-feed pipe 13 (providedwith a control valve V), t ebase 0 the chamberll be' likewise fitted with a valve V. The swive -joint 10 permits of the rotary reciprocation or panning motionbeing imparted to the receptacle as is obvious. To prevent the formation of individual or unevenupward currents of water from the nozzle 12 through the receptacle there is interposed in the path of the sai nozzle-discharge a conical spreader or equalizer 14, the apex of the cone being vertically over the nozzle 12 an on the axis of the receptacle, the base of the cone being'spaced from the walls of the hopper C by the straps or braces 15 which secure the cone to said-hopper. Surrounding the upper end of the receptacle is a launder L which receives the overflow from said receptacle. At "different elevations the latter is provided with short valve-controlled dischar e pipes, or tubes 16, 16, for testing the con itionof the contents of the receptacle, said test-tubes der L";

loid or suspended diSchaIEng into launders L, L, as shown, the int e ends of the tubes being protected by guards or aprons 17 depending into the.

receptacle, said aprons allowl the concentrates to flow down past the plpe 16, while at the same time permittin t e water to flow out of the pipes. Ina dition to serving as test-tubes,the pipes 16 may be used for purposes of lowerin the level of the contents in the receptacle 1n which event the launders L would be used to receive the overflow of water mixed with the light colclay tailings. Operating in conjunction with, and suppleillcienting the action of, the receptacle or tan ceptacle R mounted on a platform 18 having a supporting surface which allows the receptacle to assume an inclination tothe horizontal at an an le substantially as shown, but which may anywhere between thirty and forty-five degrees, such an angle bringin about the best results in washing the san from the ore concentrates. The receptacle R rests on roller-bearings 19 mount-' ed in brackets '20, the end-thrust being taken, up by the bearing-disk. or late-21 at the upper end of the standard 2 bolted o'r secured to the floor, the disk 21 being provided with an annular race-way for ball bearings 22 which are e aged by the collar or ring 243 at the inta e of the be per R forming the bottom of The upper o n end of the receptacle R is provided wit' a marginal discharge .lip 24; which discharges the overflow into a-laun- Like the primary receptacle 0, the supplemental or imparted thereto a rotary recipzocation about its axis, such reciprocation affected through the iinkeonnection 26 (coupled-to the hop r R andthe .eccentric 27 operated b e'sha S. The two receptacles C and are thus simultaneously reciprocated about their respective axes from a common shaft, the receptaicleR C is a second. or complementary re-' sulting from the up colloids said receptac e R.

complementary one. B has 25, arm

receiving the pulp discharges from the receptacle C through a bent ipe 28 leading from the chamber 11 into t e hopper R, a swivel joint 10' being interposed at the proper point to allow for rotation of the receptacle R. The concentrates or ore values are discharged from. the complementary receptacle R through a spigot or nozzle 29 located at the lower corner of the receptacle, the said concentrates being received by a launder N. p 1

The 0 ration of the concentrator may be descri as follows :-For' convenience we may assume'that the receptacle 0 is full of water and that the overflow carrying the tailings or colloids is over the upper edge thereof into the launder L. The pulp or liquid slime being fed from the mills into the funnel 8 is discharged into the rece tacle through the openings 0 in the form 0 radiating streams which collectively form a horizontal sheet, thereby thoroughly diffusing the solid materials throughout the water body in the receptacle. During the feed of the pulp into the receptacle as described, the latter has imparted thereto a horizontal rotary reciprocation or panning motion from the shaft S through the eccentric 6- and link '5, this panning in a'measure separating the ore values and sandy constituents such as quartz and ngue, from the light clay particles or col oids. The ingredients thus m a -measure separated encounter an upward risin the receptacle, re- I ard feed of the water escaping through the nozzle 12 of the pi 13, gravity'causin the ore values and San y components to fal against such rislng current, but being'insuflicient to bring down the which thus escape with the overflow into the launder L. The level of the receptacle contents might of course, be lowered by openin the valve of the up test-tube 16 and ailow the overflow to 1s charge into the upper launder L. The granular or sandy particles and ore concentrates as they fall through the r1s1ng water ass around the equalizer or spreader 14 and alling past the nozzle 12 enter the chamber 11 whence they pass into-the pipe 28. The equalizer 14 causes the .r1s1ng current to flow at a substantially uniform rate of speed throu bout the entire cross-section of the rece tac e so'that eachfalling particle may be an jected to the same current resistance, th1s equalization resulting in a more perfect concentration. The mlxtureof ore and sand flowing through the 'pipe 28 and constituting the preliminary concentrates must of course under 0 a second treatment in order that the sanf and gangue me be separated from the ore values. This pre iminary product is therefore discharged into the complementary receptacle R as already outlined, a rotary reciprocation being likewise iming current of wategv parted to this receptacle from the shaft S throu h the connections 25, 26, 27 as describe The lane of rotation (or rotary reciprocation) owever of the receptacle R instead of being parallel to the water level a: (or to the horizontal) is in a lane which is inclined thereto, thus subjecting the pulp contents of said receptacle to a wave washing action which r'esultsin athorou gh elimination of the sand and gangue, the same fiowin over the lip 24 into the tailings launder L the ore values or final concentrates discharging through the spigot 29 into the launder N; Should the concentrates tend to adhere to thesloping walls of the receptacle they may occasionally be flushed by a stream of water introduced through the spigot from a hose (not-shown).
